Fence structure

ABSTRACT

An improved fence structure includes two bases, two assembling rods, two positioning fitting heads and one fence plate. Several screwing members may pass through the base. The base has a center formed with a connection portion through which the assembling rod may be inserted. The assembling rod has several rabbet slots. The fence plate has two lateral sides formed with connection portions, which may be correspondingly embedded into the rabbet slots of the assembling rod for positioning. The center of the positioning fitting head is formed with a fitting hole to fit with an end portion of the assembling rod. Thus, many fence plates may be used to define various angular areas.

BACKGROUND OF THE INVENTION

(1) Field of the Invention

The invention relates to a fence, and more particularly to an improved fence structure, which can define different angular areas according to different occasions, spaces and sizes and can be easily assembled and used.

(2) Description of the Prior Art

A conventional fence, as shown in FIG. 1, is mainly composed of baseplates 1, rods 3 and a connection sheet 2. The baseplate 1 is connected to the rod 3 to form an inverse-T shape. The connection sheet 2 is connected to and disposed between the rods, or is composed of retractable fence members connected to a sheet. In another aspect, the connection sheet is a detachable strap having the structure composed of flexible connection bands. Because the structures are different from one another, they have their specifically used occasions and their used ranges and advantages/disadvantages. If the prior art stereotype can be overcome and the used ranges may be widened, it can bring the good news for the consumers and users.

SUMMARY OF THE INVENTION

An improved fence structure of the invention mainly includes two connection rod sets and a fence plate assembled together. The connection rod set includes a base, an assembling rod and a positioning fitting head. Several screwing members may pass through the base to screw the base to the floor for positioning. The base has a center formed with a connection portion through which the assembling rod may be inserted for connection. Two lateral sides of the fence plate are formed with connection portions to be assembled with the assembling rods, respectively. The positioning fitting head has a center formed with a fitting hole to fit with an end portion of the assembling rod. Thus, many fence plates may be used to define various angular areas.

Further aspects, objects, and desirable features of the invention will be better understood from the detailed description and drawings that follow in which various embodiments of the disclosed invention are illustrated by way of examples.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIG. 2, an improved fence structure of the invention is mainly composed of at least two connection rod sets 10 and a fence plate 20. Each connection rod set 10 includes a base 12, an assembling rod 14 and a positioning fitting head 16.

The base 12 is a quadrilateral block. The center of the block is formed with a circular hole serving as a connection portion 121 to be connected to the inserted assembling rod 14. Several through holes 122 are formed around the connection portion 121 so that the corresponding number of screwing members 123 may respectively pass through the through holes 122 to screw the base 12 to the predetermined floor. In order to match with different occasions, a base 12 a may be a triangular block formed with a connection portion 121 a and through holes 122 a, as shown in FIG. 3A. Alternatively, a base 12 b may have a disk-like shape, as shown in FIG. 3B, wherein a bearing tube is disposed or formed at the center of the disk-like base to serve as a connection portion 121 b, and several through holes 122 b are formed around the bearing tube. Alternatively, a base 12C is a rectangular plate having a bearing tube disposed or formed on the center of the plate to serve as a connection portion 121 c, and through holes 122 c are formed on two sides of the bearing tube, as shown in FIG. 3C.

The assembling rod 14 is a rectangular aluminum extruded rod having two T-shaped rabbet slots 141 with openings facing outwards on two opposite sides of the rod. As shown in FIG. 4, the fence plates 20 may be assembled with two sides of the assembling rod 14. The fence plate 20 is a plate piece having the predetermined shape and the predetermined dimension. The plate piece may also be formed with lattices or holes with many shapes in order to save the material and reduce the weight, and to provide more visual variations to enhance the glorification. Two lateral sides of the plate piece are formed with longitudinal connection portions 21, each of which may slide into the rabbet slot 141 of the assembling rod 14 from the free end portion of the rabbet slot 141. Of course, a assembling rod 14 a may also be a circular aluminum extruded rod formed with two rabbet slots 141 a, formed with three rabbet slots 141 a defining three angles of 120 degrees, as shown in FIG. 5B, or formed with four rabbet slots 141 a defining four angles of 90 degrees, as shown in FIG. 5A. The fence plate or plates 20 may slide into one or two of the rabbet slots 141 a to partition various spaces at different angles, which will be described later. In the embodiment of the invention, another assembling rod 14 d may be assembled with the top end portion of the fence plate 20 to prevent the fence plate 20 from separating from the assembling rod 14. Of course, the top end portion of the fence plate 20 may also formed with longitudinal connection portions 21 d, as shown in FIG. 6.

The center of the positioning fitting head 16 is formed with a fitting hole 161, which is concave inwards and may fit with the end portion of the assembling rod 14 higher than the fence plate 20 in order to prevent the fence plate 20 from separating from the assembling rod 14.

According to the above-mentioned members, a predetermined number of the bases 12 are screwed to the predetermined floor using the screwing members 123 passing through the through holes 122, as shown in FIG. 7. As shown in FIG. 8, because the floor is a ladder-like floor, the base of the invention may also be omitted, and the assembling rod 14 may be directly inserted into and fixed to the floor. Of course, the heights of the assembling rods 14 and the fence plates 20 may vary according to the levels of the floors. Next, the rabbet slot 141 at the suitable angular position is selected according to the shape and actual requirement in the place, and the fence plate 20 slides into the selected rabbet slots 141. Then, the another assembling rod 14 d is assembled with the top end portion of the fence plate 20. Finally, the positioning fitting heads 16 are fit with the assembling rods 14. Because the assembling rod 14 of the invention has many rabbet slots 141 at different angular positions, the fence plate 20 may slide into the rabbet slots 141 of the assembling rods 14 at different angular positions. Thus, various spaces defining various angular areas may be formed to satisfy the requirements in various spaces and places. As shown in FIG. 9, the circular base 12 b, the circular assembling rod 14 a, the positioning fitting head 16 and the fence plate 20 form the fence structure, and the rectangular assembling rods 14 d are disposed on the top end portions of the fence plates 20.

As show in FIG. 10, two sides of a fence plate 20 a of the invention are attached to two cylindrical connection portions 21 a with different heights, the assembling rod 14 is a circular rod, and the base 12 a is a triangular block. Of course, the fence plate 20 a may be directly used in conjunction with the assembling rod 14 a having the circular aluminum extruded structure according to the embodiment. Thus, a connection portion 21 a of the fence plate 20 a may be inserted into the assembling rod 14 a and may be rotated about the assembling rod 14 a to various angular positions. Consequently, multiple connection rod sets 10 arranged in a straight line may be used to constitute the fencing and railing that are frequently used outdoors. Also, three connection rod sets 10 may be used in conjunction with three fence plates 20 to form a triangular space, as show in FIG. 11, or four connection rod sets 10 may be used in conjunction with four fence plates 20 to form a rectangular space, as shown in FIG. 12. At this time, the base 12 a is a triangular block. The fence structure may be used indoors or outdoors to define the playing room, a safety area, or a feeding room for the poultry and the livestock. Thus, the fence structure may be widely used to define various spaces with various angular areas.
